FLUIDIZED BED REACTOR FOR PRODUCING POLYCRYSTALLINE SILICON GRANULES AND METHOD FOR THE ASSEMBLY OF SUCH A FLUIDIZED BED REACTOR

摘要

The invention concerns a fluidized bed reactor for producing polycrystalline silicon granules and a method for the assembly of such a fluidized bed reactor, comprising the following steps in the sequence given: setting up a baseplate (4) and connecting it to gas supply lines for fluidizing gas and reaction gas and a product take-off line (20); fitting the baseplate (4) with at least one fluidizing nozzle (6) and with at least one reaction gas nozzle (5); inserting a lower reactor pipe seal (7); setting up a reactor pipe (8) with a heater (10), electrodes (11) and insulators (12, 13) on the lower reactor pipe seal (7); positioning the reactor section (1) over the reactor tube (8); setting up an upper reactor pipe mounting (14) with an upper reactor pipe seal (15); assembling the reactor head (16); assembling the seed supplying device (17); assembling the flue-gas pipeline (18).
